Human Alliance Sideswipe suffers from botched leg articulation due to his rubber crotch pistons. People have been snipping them to allow leg movement. I offer this suggestion to future snippers:

Only cut the bottom pair of pistons, and only cut them at the very top.

A cut in that location hides pretty well behind his pointy codpiece. The top pair of pistons still hinder movement, but the improvement is quite significant. There does not seem to be any way of hiding a cut on the top pair. But the bottom pistons were the real trouble-makers anyway.
